So, at work we have a 2016 and a 2017 F150. We have an issue with the 98 mph speed limits that are on the pickups. I have been curious, is there a way to override the limit? Next spring I will possibly be getting a 2018 issued to me, and I am thinking it too will be slow!
I have the forescan program with the elm327 device, is there a way to over ride the speed limit with that? Or is there a programmer out that will bump the power and speed up a little?

 

And what`s your profession and why would you need to go faster?

There are reasons specific vehicles are limited to a certain speed.

 

Based on his username, I'd guess he's in law enforcement. How does this help the OP with his question?


True, and the lowest common denominator is usually tires. I'd check the tire's speed ratings before removing the speed limiter. It would require a tuner of some flavor, but it's relatively simple to do.

 

The speed limiter keeps you from going faster than the speed rating of the tire. This is also why many tire shops won't put a tire with a lower speed rating on a car / truck than what it came with. Tires are made with a specific speed and load ratings, If you exceed either the tire can have a catastrophic failure.

With that being said, I'm sure there are some plug in tuners out there that will give you access to the speed limiter.

 

I just looked it up, the OEM tires on the F150 are "T" speed rated, which is up to 118 MPH.

 

THis will give you an idea of what's available out there.

But I would suggest you discuss this with your fleet manager before you modify the vehicle. Ford is pretty tough on fleets when it comes to operating outside the scope of the vehicle design.

 

Sounds like a good way to get killed or fired if you ask me.

 

Yes, our pickups are used for emergency services, that is where the desire for a little more speed comes from.
The way these Fords handle at high speeds we don't want to get much more out of them, but 110 would be nice. Typically on an emergency call we don't have a need for much over 100, it is too dangerous considering the few seconds that are saved in the travel time but once in a while it would be good to get a little more.
I am aware of the dangers of the tires at high speeds. I don't remember what tire we are running on the Fords, it was recommended by our tire supplier for the higher speeds we do run. We usually don't keep the factory rubber on them long after the vehicle is put in service. We also add weight to the back end of the Fords when they go into service. The light weight pickups don't handle well at all over 90 without an extra couple of hundred pounds in the box!
Thanks MSGTord, that is the information I was looking for.
I know that modifying things could void the warranty on the engine or transmission, but I am not sure how good the warranties would be to start with. Dealers have always hinted that the warranty on the engine or transmission might not be honored because of the rough service we put or pickups through.

 

Our 2017 hits 105mph with ease...i wonder why the one you have is limited to 98...4wd?

 

My 2015 3.5 EB 4x4 shuts down at 105 or so.

 

You also need to consider the driveshaft critical speed. The speed is different for each vehicle. Here is a video of what happens when you exceed that speed.

 

Those poor V6 mustangs saddled with Chinese driveshafts...numerous reports of them breaking on the dyno too. I wonder what ours are good for.

 

Yes, I saw his username but does that automatically and 100% verify that he`s in law enforcement?

Have a great day.

 

That wasn't my point. Someone came on here asking a technical question looking for answers. He wasn't looking for an inquisition on his employment or driving habits.

 

Lol...Thank you.

Removed the limiter, higher speeds are increased, aerodynamic designs are exceeded, vehicle becomes more unstable with increased air under said vehicle, driver loses control and perhaps injure or kill himself or other people, etc, etc, etc.
